The USB chips came in today and I have a finalized schematic.  My 
business partner is laying out the board now.  I'm just going to have 
some prototypes made with silkscreen (can't do it in my shop) because 
soldering the fine pitch microcontroller and USB chips would be a pain 
without solder mask.  I'll be making five prototypes...2 of which I'm 
going to hand off to people for development/testing.  I'll need reports 
on IR reception and transmission, LCD functionality, and overall 
thoughts on the design.  I'd prefer someone with at least minimal 
electronics experience and, ideally, a device programmer capable of 
programming a Microchip PIC18F442.  Knowledge of drivers for LIRC and 
LCDproc is also essential since minor modifications will need to be made 
to existing ones.  I'm putting a bootloader in the firmware so that 
upgrades can be made serially, but if things go REALLY bad, you'll need 
a programmer to reflash the chip.  I'll send these people firmware 
updates based on their bug reports and my progress.  In the end, these 
two people will get a free produciton unit.  Is anyone up for the challenge?

Steve
